The tank has a space and a cover. The cover is detachably disposed on the tank to close or open the space selectively. The access opening is in communication with the space of the tank. The first dielectric liquid is accommodated within the space to form a liquid surface. The liquid surface and the access opening are disposed adjacent to each other. The working object is immersed in the first dielectric liquid. The condensing unit is arranged in the space above the liquid surface. When a cooling operation is performed, the access opening is closed, the first dielectric liquid is kept in the space, and the heat generated from the working object is dissipated through the first dielectric liquid and the condensing unit.

Abstract: A photovoltaic-inverter heat-dissipation assembly is disclosure and includes a front housing-base, a rear cover, a first heat-generating device, a first fan, a second heat-generating device and a second fan. The rear cover and the front housing-base are combined to separately form a first heat-dissipation space and a second heat-dissipation space. The rear cover includes a first air-inlet, a second air-inlet and an air-outlet. The first air-inlet and the second air-inlet are in communication with the air-outlet through the first heat-dissipation space and the second heat-dissipation space, respectively. The first fan generates a first airflow, which enters through the first air-inlet, flows through the first heating-generating device accommodated in the first heat-dissipation space, and flows out through the air-outlet. The second fan generates a second airflow, which enters through the second air-inlet, flows through the second heat-generating device accommodated in the second heat-dissipation space, and flows out through the air-outlet.

Abstract: A bidirectional power supply includes an alternating current (AC) port as a source in a first mode and as a load in a second mode and a line-frequency rectifier/inverter to function as a rectifier in the first mode and a set of switches to function as an inverter in the second mode. A bidirectional resonant converter is coupled to a direct current (DC) port with primary-side switches and secondary-side switches respectively arranged on a primary and secondary side of a transformer. A controller controls the primary-side switches and the secondary-side switches by controlling switching frequency based on a determined value while setting time delay between control of the primary-side and the secondary-side switches to be a predefined time delay or by controlling the time delay between control of the primary-side and the secondary-side switches based on a determined value while setting the switching frequency to be a predefined switching frequency.

Abstract: A power converter is provided. The power converter includes first to fourth switches electrically connected in series, a flying capacitor and a controller. Positive and negative terminals of the flying capacitor are electrically connected to the second and third switches respectively. The controller operates the first and fourth switches to perform a first complementary switching with a first dead time, and operates the second and third switches to perform a second complementary switching with a second dead time. The controller determines to regulate the first or second dead time by detecting a capacitor voltage of the flying capacitor, such that the capacitor voltage of the flying capacitor is maintained within a balance voltage range.
